CVE-2013-7268

Published: 06 January 2014

The ipx_recvmsg function in net/ipx/af_ipx.c in the Linux kernel before 3.12.4 updates a certain length value without ensuring that an associated data structure has been initialized, which allows local users to obtain sensitive information from kernel memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg system call.

From the Ubuntu security team

An information leak was discovered in the recvfrom, recvmmsg, and recvmsg systemcalls when used with ipx protocol sockets in the Linux kernel. A local user could exploit this leak to obtain potentially sensitive information from kernel memory.
